Re: native i/o and RCAC - performance

Physically, yes, but through an abstraction layer. The OS is unaware of
the physical devices providing nonvolatile storage (magnetic disks and
SSD's); the beauty of this approach is that underlying hardware changes
(new storage technology) don't affect the OS and what we users
(programmers) see. One other consideration: after implementing a new
device type, regression testing is way easier because you don't have to
test the OS, just up to the interface.

The hard disks allocated in ASPs are part of the SLS. What you probably
wanted to say is "… sitting in RAM".

:wq! PoC
